PURPOSE:To eliminate constant placement of a skilled person by storing a speed reference manually corrected in case of altering an operating state in a continuous process line for sending and winding a material to be conveyed, and employing the correction value in a next operation. CONSTITUTION:When changeover switches 14a, 14b are opened and line seed setting means 8 generates a speed reference signal V1, a draw is set by a setter 9, a speed V2 is applied to speed control means 10 to control a sending motor 2. The signal V1 is drawn by a drawer 11, a speed V3 is applied to speed control means 11 to control a winding motor 5. When a material to be conveyed such as the width of a sheet is varied in this state so that the sheet is slacked or tensioned, an operator adjusts the means 11 at each time to minimize variation in the speed. Automatic draw setting means 15 stores difference (V3-V1) of the speed at the respective times. When a series of conveyance is ended, the switches 14a, 14b are closed in next conveyance to operate the means 15. Thus, constant placement of a skilled person is saved. |
